i want to get corsa catback and am going to get it on cobalt-addiction.com what's better the sport or touring, and it's 4" tip how is that? it's same price and what's difference.



1 more question, kinda stupid i'm new to this stuff still, but if i get a GM stage 2 upgrade do i need to get a stage 1 first or is it like sorta included.

 

Sport is more aggressive (loud) the touring is a bit more "tame" and sounds REALLY good, most go with the touring.

You can get the GM stage one then get the GM stage 2 OR you can go right to the GM stage 2. There are 3 different part numbers the GM stage 2 i think retails for $750. Stage one is $400 and stage 2 "upgrae" is 500... I think this is right.

So you save $150 by going right to the stage 2.

Email us on the corsa if interested we can price match or maybe even do better than that.
